OK, I was right on the verge.  My original had it reading
from a file, which I opened with fopen(filename, "r").
Then in trying to isolate the problem, I converted to stdin
and still had the problem.  Then (I know, wrong order) I
read the docs and for some silly reason modified
my *write* open to fopen(filename, "w") to fopen(filename, "wb").

So, I was on the right trail; just not thinking hard enough.

Any way to change EOF to ctrl-D like real UNIX (and to reset
interrupt)?  I notice that there is no bash command like stty.

Many thanks for the assistance.

Bob
